Title: Damper winding for rotary electric machine
Inventor: TOSHIMA HISASHI
IPC: H02K19/14
Filed: 1987-03-30
Abstract: PURPOSE:To prevent a connecting piece from being deformed due to a centrifugal force, by engaging a bearing member with a short circuit piece. CONSTITUTION:A bearing member is composed of an internal bearing 1 engaged with the inner diameter side of a short circuit piece 6, and an external bearing 2 set in contact with the outer diameter side of a connecting piece 7 and fixed by the leg 1a of the internal bearing 1. Accordingly, even if the central section of the connecting piece 7 is forced to be deformed in the outer diameter direction by a centrifugal force due to rotation, its action is constrained by the external bearing 2 and so deformation is not generated. In other words, the centrifugal force of the connecting piece 7 and the centrifugal force of the external bearing 2 are transmitted to the internal bearing 1 via the leg 1a, and the bearing 1 is supported by the short circuit piece 6. In a groove 1b, a slight void 1c is set in the peripheral direction, and elongation in the peripheral direction due to the thermal expansion of the short circuit piece 6 is absorbed not to be constrained, by the curved section of the connecting piece 7. In this manner, the bearing member is not continuously jointed to a yoke 10, and so by an elongation difference between the yoke 10 and a magnetic pole, the connecting piece 7 is not deformed.

Title: Heterojunction bipolar transistor
Inventor: TSUDA KUNIO
IPC: H01L29/737
Filed: 1986-04-02
Abstract: PURPOSE:To decrease base resistance without decreasing gain and to shorten the base running time of minority carriers, by constituting a bipolar transitor, in which an emitter-base junction forms a heterojunction, and forming a base layer with a thin film, in which impurities are doped, and an undoped layer. CONSTITUTION:In a base layer, four AlxGa1-xAs layers 31 each having a thickness of 30 Angstrom  and four GaAs layers 32 are alternately laminated. The total thickness of the base layer is 200 Angstrom . All the AlxGa1-xAs layers 31 are not doped. The mol ratio X of Al is linearly changed from 0 to 0.1 at a thickness of 200 l from the collector side to the emitter side. The layers 31 are formed so as to corresponde to the slant of said ratio X. In each GaAs layer 32, a planar doped layer 33 comprising P-type impurities is formed at the center. Since the doping into the base layer is planar doping, the concentration is as high as 1 x 10<20>cm<-3>. Since the lateral mobility of holes is high, the base resistance is suppressed to a low value even if the base thickness is as thin as 200 l.

Title: Small-sized boat
Inventor: FUKUNAGA HIROYASU
IPC: B63B5/24
Filed: 1983-04-27
Abstract: PURPOSE:To shift the center of gravity of a small-sized boat in accordance with the weights of crew-members and cargo, to secure/the buoyancy and strength/thereof and thereby to ensure the stable steaming, by arranging a lower opening for water filling, an upper opening for ventilation and a buoyant body for partitioning a vacant chamber in the vacant chamber provided on the double bottom of the boat. CONSTITUTION:When a crew-member is only one and cargo is little, a rubber plug of each draft pipe 15 is removed so as for the pipe to communicate with the outside air. Then air in a vacant chamber R goes out, and water flows into the chamber R through an opening 13 of a hull 11. The water flowing in through the opening 13 is distributed to the right and left sides of the vacant chamber R on the occasion, since a buoyant body 14 disposed in the chamber R is positioned in the central part of the front section 10 of a small-sized boat B, and thus the water can be let in without impairing the stability of the boat B. When the water flows in to the full, the opening at the upper end of each ventilation pipe 15 is closed by the rubber plug so as to prevent the water in the vacant chamber R from going out and thereby to secure the stabilized state of the boat. When there are many crew-members and much cargo, they can be carried without removing the rubber plugs. The buoyant body 14 reinforces the small-sized boat B, increasing the buoyancy without impairing the property of light weight, since it is made of foamed styrol.
